Abstract (en)
[origin: EP1624540A2] The motor (10) has an armature (11) with a current collector (16) with brushes (12,14). A permanent magnet (18) is used instead of a field coil. The motor current (I) is supplied by a motor control circuit (24) containing a microcontroller module (26) with multiple inputs (32-40). The control module passes a square-wave to an end-stage (28). The motor control circuit has a positive pole (20) and an earthed pole (22). The current return line (42) from the motor is connected to one of the inputs of the control module. To a control input (30) for the microcontroller module.
